KENNEDY SPACE CENTER, FLA. - Viewed from the floor of the Vehicle Assembly Building, the redesigned External Tank is seen being lifted to the top where it will be lifted into the "checkout cell" where the tank?s mechanical, electrical and thermal protection systems are inspected. The tank will also undergo new processes resulting from its redesign, including inspection of the bipod heater and External Tank separation camera. The tank will be prepared for "mating" to the Shuttle?s Solid Rocket Boosters. When preparations are complete, the tank will be lifted from the checkout cell, moved across the transfer aisle and into High Bay 1. It will be lowered and attached to the boosters, which are sitting on the Mobile Launch Platform. The SRBs and ET will be flying with Shuttle Discovery for the Return to Flight mission STS-114. The launch planning window is May 12 to June 3, 2005.
